3 Claims.

The invention herein disclosed relates to radiators and is particularlydirected to that general type of radiator adapted for use as a unit ofthe water cooling system of an internal combustion engine. Morespecifically the invention concerns what is generally referred to as theradiator core and which ordinarily includes a plurality of spaced watercirculating tubes or conduits 'associated with suitable means forentraining cooling air between said tubes or conduits, it being anobject of the invention to provide an improved radiator coreconstruction including air entraining means between adjacent fluidcirculating members with said air entraining means formed to provideseries of transverse air passages extending from front to rear of saidcore and to provide air deflecting elements arranged to split the airentrained through said passage and deflect the split air currents intothe adjacent air passages.

Another object is to arrange certain of said deflecting elements todeflect some of said split air currents towards said fluid circulatingmembers and to arrange other of said deflecting elements to deflectother of said split air currents away from said fluid circulatingmembers.

Another object is to angle said deflecting elements to deflect saidsplit air currents obliquely to increase the cooling effect of saiddeflected split air currents by thus increasing their distance of travelbefore being discharged from the radiator core.

A further object is to angle some of said deflecting elements upwardlyand rearwardly to direct some of said split air currents in an obliquedirection upwardly and rearwardly across the adjacent transverse airpassages and to angle others of said deflecting elements downwardly andrearwardly to direct others of said split air currents in an obliquedirection downwardly and rearwardly across the adjacent transverse airpassage. 7

Another object is to provide additional reversely facing similardeflecting elements whereby the air entraining means will functionsimilarly on air entrained through the radiator in either transversedirection.

Various other objects and advantages will be more fully apparent fromthe following description of the accompanying drawing which forms a partof this disclosure and which illustrates a preferred form of embodimentof the invention.

Fig. '7 is a front elevation of a further modification in which a singleair-deflecting plate is asthe line 3-3 of sociated with two adjacentparallel straight fluid circulating conduits.

The core of a radiator of the general type to which the presentinvention relates, usually comprises a plurality of vertically disposedfluid circulating conduits spaced apart by means constructed to provideair passages through which cooling air is forced to effect a transfer ofheat from the conduits to the air entrained through the core. In thepreferred embodiment illustrated in Figs. 1 to 4, the several fluidcirculating conduits or water tubes A are disposed vertically intransversely spaced relationship and are separated by intermediateair-deflecting units B. Each tube A is preferably formed of a pair ofrelatively thin plates 10 and 11 transversely corrugated and disposed tointerinesh with each other, the intermeshing longitudinal edge portionsbeing joined together at l2, l2 and their intermediate portions beingspread apart to provide a zig-zag fluid passage 13. At opposite ends ofeach crest these plates 10 and 11 are provided with pairs of relativelyshort ridges 10 and 11 defining relatively short intermediate indents orpockets which receive the respective crests of the adjacent corrugatedair-deflecting plates as will later be more particularly described.

The several air-deflecting units B are of duplicate construction, eachcomprising a pair of relatively thin plates 20 and 21 transverselycorrugated and disposed in erest coengaging relationship to provide avertical series of inner air pastwo air-deflecting plates and the outercrestsof 1 said plates engage the adjacent fluid conduitsi n the pocketsformed by the respective ridges" 10 and 11 thereof, these tangs andridges thusl providing means for maintaininglth'e; partsin properalignment during assemblings. 'In the manufac ture of the core it ispreferable to first assemble the several parts and their secure theassembledw parts together, by dipping the assembled core in--- moltensolder or in any other suitable manner, to form a permanentlyJ'Oinedunit;

The twoplates 20 and 21 forming; each-air-de fleeting unit B are ofduplicate contour and const-ruction but when; brought together increstcoengaging relationship they are first transversely reversed, thatis, theyare turned-so as to bring one longitudinal edge of each plateadjacentthe oppositelong-itudinal edge of the other plate. This will beunderstood from an examination of Fig. 4 wherein the tangs; 2 0 oftheplate 20. are positioned towards the-rear of-the core while the tangs 21of the plate 21 are positioned-towards the front or" the core=-Describing each-of the air-deflecting. plates sep arately, a-transversewal-l 20 on one side of each inner crest 20' of the plate 20-is providedwith apertures 20 disposed-at transversely spaced intervals, and isdeformed adjacent the rear edge of each of said apertures. to providedeflecting elements 20 projecting into the adjacent inner air passage Band facing the entrance end-of said'passage. The transverse wall 20?;011the other side of each inner crest 20 is providedwi-t-h similarapertures 20 disposed at transversely 4 spaced intervals staggered with:relation to the aperturesZO of the opposite. wall and saiel' wall 20 is;deformed adjacent the rear. edge of reach of said apertures to provideother deflectingelements 20 projecting into the adjacent. outer airchannel B and facing the entrance end'. of said channel. The severalapertures are preferably formed by slitting. the plate so that thedeformation of the wallto formthe deflecting elements will open theseslits toprovide the apertures and the several slits are preferablydisposed vertically although they may be other than straightlverticalslits. The air-deflecting plate 21Tis' provided with similarly formedapertures andv deflecting elernents,-the-transverse wall 521' on oneside of each inner crest 21 being providedwith apertures 21' disposed attransversely spacedintervals and being deformed adjacent; the rear edge,of each of I said apertures tc-providfe, deflecting elements2lprojecting into the adjacent outer air channel B and facing theentrance. end ofsaid channel. The transverse wall; are on the othersideof each crest 21 is provided withthe apertures .21. dis!- posed attransversely spaced intervals staggered with relation to .the apertures21! of the opposite wall and said wall 21 isdefo'rmed adjacent the rearedge of each of said apertures t'o'pr'ovide other deflecting elements 21m ecung inw the adjacent-inner air passage B and-facing the e ri tranceof 'sai diairpassagek With these deflecting-"elementsprojecting-into.in'the respective outer air channels B and deflect such split aircurrents away from the fluid conduits A and through the associatedapertures 20 and 22L into the adjacent air passage B as indicated bythearrows 31 in Fig. 3. With the rel atively staggered -disposition ofthese several deflecting elements, .air currents are successively splitfrom-ans recombined with the air bodies passingqthrough the several airpassages B and B and since the adjacent walls of these air passages aredisposedin different: oblique directionsthe' deflected air. currentswill be directedtin laterally opposite oblique directionsr Thisarrangeine-nt extendsthe'path oftravel of a substantial part of theentrained air to appreci- 'Ii-EO ably increase its effectiveness-in'cooling-the fluid conduits.

To further extend the'path' of travelof th'edeflected air currents, thedeflecting .e'lementsare angledg. the deflecting elements.20' and 20 ofeach plate 20 being angled upwardly and-rearwardly' to direct theaaircurrents deflected thereby obliquely upwardly and rearwardly; asindicated" by the arrows 32 in Fig.4, and theideflecting elements 21 and21 of 'each platezl being angled downwardly and rearwardly to direct theaincurrents deflected by these deflecting elements obliquely downwardlyand rearwardly,: as indicated by the arrows"33in Fig. 4. r

This cross flow of the deflected air currents from front to rear of theradiator core in opposite oblique directions transversely andlateral-lyand across adjacent air passages substantially contin'uouspath'spromotes relatively long travel of the deflectedair currents -throughthe radiator 1 0 core to contribute greatly toa nia-ximum cooling or thefluid conduits by the cooling air.- In the preferable embodiment or theinvention it is desirable to provide aradiat'or core which may be usedwith 'either side? facing the source-of cooling air or that wil l'functi'o'r r the sameonair forced through the air passages in eithertransversedirection andtothis e'nd =the plates 20 and 21 arealsodefornied adjacent theforw'ard' edge of each of theseveral-apertures toprovide 'additio'm al deflectinge1ernents 20, 20";21 and 2l sim ilar to the respective deflecting elei-iiehts 20-; 21 2-1and 21; exce tin that they" face the opposite endsof the air passages. i

In Fig. 5 only one of the air-deflecting plates is associated with twoadjacent zig-zag fluid conduits and in this modification the deflectedair cur-rents are directed only 'in-one'transv'erse obliqu'e direction;1

In- Fig.-' 6 the air-deflecting unit comprising the pair of-air-deflecting plates as above described, is shown associated with twoadjacent parallel straight fluid conduits; while' iri Fig. 7- asingleair-deflecting plate I is shown associated with two of suchstraightfluidconduits;

Throughout-thisdescriptionsuch terms-as ve'rtical, front; rear,upwardly-, downwardly and rearwardly, areused in a relative sense' 'itbeing obviou's that the 'descri'b'e'd radiator' may be used not only inavertical position-but in any other 9 position and that the air may beforced therethrough from either the front or the back.

While the form of construction herein illustrated and described is fullyadapted to fulfill all of the objects primarily stated, it is to beunderstood that we do not wish to limit the invention in this regard,for it is susceptible of embodiment in various other forms; all comingwithin the scope of the following claims.
